It is not really just a measure of intelligence and education (those help) but how our brains work and how we identify our values. Some of us have an internal moral/ethical foundation that is very strong, some of us need an outsider to tell us these. Some have clearly defined values while others need someone to tell it to them. Some people want to live in their fictionalized authoritarian utopia, because they are lazy and happy, and can easily ignore what isn't happening to them, or dismiss what happens to others as simple hysterics. Christians and Republicans often lack these internal values/ethics. I did ask my father "What could Trump do that would make you not vote for him? " and his answer was "nothing."
That clearly pointed to a lack of values/ethics and how this has moved into what @TahoeHorn accused others of, identity politics/cult of personalities. That is all this is to them. A game, a reality TV show, and a fictionalized struggle against the forces of evil: Jesus, freedom, choice, education, science, and at the root of it, responsibility.
